It's a little hard to tell from your picture but it looks like I see reels at each end so, yes! Please tell me about your rig. Would it be possible to make a 120/135 version?

Definitely something I've been considering. However, there are very few full-roll scanners on the market. I currently own one, the Pacific Image XA. It's pretty good, just slow, and occasionally has frame alignment issues. I am getting a Fuji Frontier SP-3000, but this scanner just doesn't do a great job with chromes.

Also, this will be a stage in my process:

Question about the current Pentax Film Duplicator & a mod

So, the film duplicator is a little tough to get info on. But maybe someone here has seen it or can still answer my question...

1. I know it's designed to be used around flash. This design decision probably pre-dated pixel shift tech, which seems uniquely suited to duping high resolution films. Is it possible to rig up a good continuous source?

2. Has anyone handled the strip film holders? What I'd be interested in doing is rigging up a sort of manual feed reel to reel system where I can go frame by frame through a full roll of film. Does the film move easily through these strip feeders? Would this be possible at all?

So people understand, I'm starting to do scanning for clients here in Maine. Most of the time I get full rolls, and I don't think that Fuji Frontier's do a good job of scanning chrome. I have a desktop unit that can do full rolls but it's slow as molasses, and in theory a Pentax K-1 using pixel shift could probably eek out most of what a Velvia frame is putting down... I'd just like to make a system where I can do something like, take 2 120 reels, and feed the roll through the duplicator. I could shoot the K-1 tethered and use pixel shift or even multi-exposure on each frame. But this would only work if I can rig up a continuous light source, and move the film easily through the film holder.

I wish I could demo the thing but nobody has it! Seems like I have to special order it...

Does anyone know if you HAVE to use a Pentax camera? From what I can see it doesn't really look like you do.

Churches are one thing, people aren't moving too fast. A dark reception is a whole different animal. Those are basically NO-LIGHT situations. Lets be honestly these days with ISO 12,800 being usable in a small print, if there is any light at all, you have the option of not using flash. However when you are in the dark, and you need to lock your lens on target and fire a strobe, IR-AF can't be beat.

Sounds like a trumped up AF assist lamp. This is far more irritating to wedding guests at receptions and in my experience not as fast or accurate. The little IR beam finds perfect focus nearly instantly and the red light doesn't blind people or even make them aware they're about to be photographed.

That thing was hard to focus on the Contax! You could try a better focusing screen from Bill Maxwell, that should give you a clearer idea of your true DoF. Also Sam Hurd might advise you to embrace live view as he does with wide open lenses up close. Fast Planars always have a very thin line of focus, and a veil around that area. The 50/1.4 Planar is almost impossible to focus without an EVF at 1.4.

I'm going to be a bit contrarian and say I cannot recommend the Sigma 35/1.4 Art. I had one for a while, and sold it. It's extremely heavy for a lens, and with the K-3, it'll be a front loaded beast. While it is very sharp, it is also quite boring in it's rendering, with contrast that makes you go...'meh'. IMO people should get into the Pentax brand because their lenses seem to me to be designed with aesthetic rendering first, and measurbation 2nd. The 43/1.9 is an old design by modern standards, but extremely sharp, especially when stopped down even at 2.8. It also has fabulous rendering and contrast, a tiny profile, and mechanics that are simpler than the Sigma (simpler = more reliable). "Image Quality" is a meaningless term when you consider that all the variable that make up the quality of a photograph. Even if the 35 is a hair shaper than the 43, I prefer image qualitIES of the 43. The best lenses balance sharpness, contrast, and rendering to make a whole. The reason why the Otus line is still better than the Art line, even though sharpness may be similar, is that the Zeiss bring the rendering too and balance them both.

As for the 55, well if you want a Portrait lens thats the one to get. The 43, 35, and 30 are more general purpose. Also, consider the 31/1.8 Limited! If you're looking for something wider than the 43 that's the one to get. Sharpness and rendering for days.

In short, you can't answer my question as you apparently have not used the K-1, do not shoot weddings with wide open lenses, and therefore have nothing to add to this conversation. The title of the thread is "Can anyone with a K-1 give me a review of the AF?" If you do not have a K-1, you have nothing to add by default. Feel free to post an essay somewhere else about your general feelings regarding AF reviews of cameras you don't own.

Yes, you missed the part about consistency. If I shoot with a 645z, and film, I don't want the format of my vertical digital images and portraits suddenly changing to 3:2 when I switch cameras. 3:4 fits on an album page better, and is simply a better headshot compositional format. Sure you may have made nice pictures in 3:2, I'm not saying it CAN'T be done, but I want my work to be consistent and with a digital camera there is no reason why I shouldn't be able to shoot in nearly any aspect ratio in camera.

If they want to do Pentax users a favor they'll have integrated in-finder 4:3 crop. This will not only make it an even more perfect 645z back up, but also give photographers a portrait format that actually makes sense. The fact that almost all cameras exclusively shoot 3:2 only is absurd since digital cropping is so easy. I have to go through and crop and adjust every damn wedding image and it's a PITA.

Hi! I'm pretty excited about the K-1, but one area where Pentax has been only adequate vs the competition is in AF. They make very accurate AF, but it's not really fast and the point spread is weird sometimes. I'd say my 645z keeps up with the old 5D Mark II, with a few extra points for low light accuracy. But my DSLR is the D750, which aside from the D5 probably has the best AF of any FF DSLR. How does the K-1 measure up? I shoot weddings so I need a camera to track slow moving subjects reasonably well, and lock focus at a dark reception reasonably quickly, ESPECIALLY with fast lenses. As an example, I had to upgrade to the D750 from the Df because the Df simply could not focus the 58mm 1.4G wide open, it would consistently miss. The D750 nails it every time, it's remarkable. But I'd switch to the K-1 in an instant if it offered even 75% of that performance.

I personally can't imagine that the Astro crowd wouldn't be currently satisfied by the A7RII and the Batis/Loxia offerings. 25/2, 21/2.8, 18/2.8... I know from my RX1RII that the BSI sensor is a true upgrade. It nearly competes with the Z in some ways.

A lot of those Contax shooters are pretty attached to film. The rumors of film's demise are greatly exaggerated as they say, certainly here in the USA where we have multiple lab choices and plenty of Portra. 400H is extremely popular too but I don't trust Fuji to keep it around.

I shoot professionally in NYC and have a reasonable sized network, and nobody who makes money with their camera is shooting Leica S. If they WANT to spend that money it's better served with a Hasselblad H5D, and if they don't the 645Z is the obvious choice. Contrary to popular forum opinions pro's do look at price and the Leica offers nothing in terms of real ROI over a 645z, or film, or a FF kit. I do know some portrait pro's who've integrated the M system into their workflow but it's always augmented by a 5D, D750 or similar. Plus the word I've gotten is that the Leica 007 is worse at high ISO vs the Z. The CCD bodies are a complete non-starter. If a Contax 645 shooter needs FF digital they're mostly out of luck. It's the shutters in the bodies that are the weak link, and scarcity of parts generally. Even if Phase One offered the 100mp back in Contax mount at $10k (so complete fantasy land), it would be a hard sell unless someone started officially supporting the bodies, or better yet, making new ones. It's a damn shame because the Contax system itself is fantastic. It's really a shame that it was so short lived.

The only problem I see is that Pentax's new lens price targets are a bit high so far. As much as I want a fast prime for Pentax I might balk at a $4000+ price tag. The 90mm is way over priced IMO. I'm not sure why the 90 is so expensive while the 55 and 35 are so comparably affordable... The 28-45 I can understand as it's got SR and is probably best in class.

Also the 28-45, until 35mm AFAIK. Personally I'd rather just use the DFA 35 HD on film anyway. And...I dont' think there was every anything wider than 35mm for ANY 645 system in the film days. So I definitely don't feel like I'm missing out on anything.

I've been saying this since the Z came out! Mamiya had the 80/1.9, Contax has the 80/2, Hasselblad has the 110/2 and the H system as the 100/2.2, the 67 system has the 105/2.4...I'm not sure what Phase has... But the P645 system has always been left out when it comes to a fast lens! It's really a shame because the Z has the best AF of any system so a fast lens would be the most usable. Hopefully they make this happen. Something tells me though after the zooms, they'll make some leaf versions of the 55 and 90.

If you want some fast glass The Bokeh Factory can provide it, but it's going to be manual focus only. I myself am planning to get their 90/2 Summicron that they re-housed to Pentax mount. :)

The Contax 80/2 was autofocus and not very heavy. Neither are the 2.4 lenses for Leica S, and the Hasselblad 100mm 2.2 is a very reasonable size. As for cost, hopefully they can keep it under $2500, but this IS medium format we're talking about. For many users, it is worth the cost and the added weight. Myself included.

I obviously meant the 45-85, and made a typo.

So your point seems to be hinged on the premise that Pentax cannot produce new lenses concurrently with a new camera. News to me. Did Pentax announce that they've suspended development of new lenses for 645? They still have a roadmap. The two lenses on the roadmap are replacements for the 24-85 and 80-160, which I would argue should be low priority next to an F2 lens in the 75-85mm range and leaf versions of the 55 and 90mm. But I will concede that people use zooms so maybe there is a big market for them.

However, what if they CAN keep on releasing new lenses AND a FF 645 camera at the same time??? Because if they spent two or three years releasing a bunch of DFA lenses w/o taking advantage of a new sensor I can tell you what people would be saying... "Pentax won't go FF again, why won't Pentax go FF??" I can pretty much guarantee you that will release a FF 645 with maybe one of the planned zooms, or both, and that over the next few years you'll see maybe 1 new 645 lens per year. Exactly as it should be.

And I would 100% agree with you that there should be new developments in these lenses. A new 150/2.8 with SDM and WR would be welcome. I'm only arguing that Pentax should not suspend camera development, and that there are more than enough lenses to get going until that happens. I really want to pick up that 110 f2 as well, but the adapted 90/2 Summicron seems a bit cheaper so I'll probably go that route.

Where exactly is the insult in my question? Calm down.



I just find this a bogus argument. Lets look at the FF compatible glass that's modern. You have the 35, 55, & 90 macro. Medium format isn't like 35mm where people build up large collections of glass. I don't know what I would do with more lenses than those three honestly. They would need a new FF 'normal' but otherwise, I'm good. If you can find me an image that was ruined by the 55/2.8s field curvature I'd love to see it. Because unless you're pixel peeping a brick wall, that lens is fantastic. Photographers who actually make pictures that are enjoyable to look at, don't have problems with the 55/2.8. Pentax is not a brand that plays in the test-chart-olympics. If that kind of stuff is important to you, seriously go buy an A7RII and the 3 Otus lenses and start posting in forums about how medium format is dying. You'll be happier.

The DFA lenses will be useable in crop mode. Problem solved. Plus I bet that the 28-45 starts to cover at 35mm.

Then you have the classic FA glass. It's a mixed bag to be sure, but people don't seem hampered by the various choices if you actually look at images being made. If you're not a pixel peeper, you can do some amazing things. The telephotos appear to be pretty fantastic. I've seen some killer wildlife images made with them.

Then you have the 67 lenses, they're manual focus, but lots of them are killer. And before you start about chromatic aberration, lets remember that LR exists and so chromatic aberration is no-longer a problem.

Lots of Hasselblad owners have been using Phase One backs and now CFV backs on their traditional V system cameras for years. The P45+ on the 503CW was THE TOOL back in my early days of studio work. We weren't complaining about the old Zeiss glass. The H glass is pixel peeper better but it's not like the Zeiss designs are suddenly garbage. Well guess what, a $50 dollar adapter puts all that sweet Zeiss glass on your Pentax camera and you can bet it sings on FF 645. AND it's actually easier to use on a Pentax because of focus confirmation and a competent live view. Legendary lenses like the 100 Planar, the 110/2, the 40 Distagaon, the underrated 60mm Distagon are all still just as amazing as they were on Velvia as they are on 100mp. Pixel peep them you might find something, but again if you're an image maker, you're in heaven.

If you're a portrait person like me, you can do what Gavin did and get mods from the Bokeh Factory and have some really unique glass. Gavin went with the legendary Contax 80/2 Planar (a lens that pixel peepers hate but talented photographers world over love), but I just saw that TBF is now adapting the old M 90/2 Summicron and it as full aperture control. Both cover FF 645 and will be amazing for portraits.

So already you have the most lenses available for any medium format system, and I'm not even counting the old A glass.

Are the line ups for H and Phase cameras more modern and probably better for pixel peeping? Sure. But we're talking about camera systems that require $20-30k+ plus investments w/o considering the glass. And if you actually USE those systems you'll know that they're not actually that fun to use on location like the 645z. They are without a doubt the in-studio tethered champs, but they can't go where the 645z can go. Different horses for different courses.

Basically the TL;DR of my post is that you don't actually need lenses 'designed for digital' and pixel peeper sharp to get out there are start shooting. Telling Pentax to ignore what they other two players have done and to stay crop is why professionals abandoned Pentax when they could't release a FF under Hoya. The K1 is the most buzz generating Pentax since the 645D and Z were released. They'll continue to slowly put out new lenses I'm sure, but in the mean time they'll put out what are in my mind the finest cameras on the planet with their 645D, Z, and 'X'. I'll use the 75/2,8 FA on it just like I do on my 645N, and it'll still be a great little lens.

Honestly anyone unsatisfied with the gift that Pentax has given us considering the price of the Z should put their literal money where their mouth is and pick up a Phase One XF and an IQ3 100 back. Brick walls and test charts await! :-)

---------- Post added 04-09-16 at 05:17 PM ----------



You will honestly get an H6D100 for 30+ grand just to avoid waiting a year for the extra real estate? I really don't think the Z is holding you back man, and keep in mind the Z has multi point AF while the H system is still only single point. The 645X is most likely going to have the K1s AF and that'll be a big freaking deal for wedding people like us. That 80/2 would indeed be amazing on FF but I think a little more patience and you'll get it and more. You'll also be losing 1/4000th of a second which is nice to have when shooting wide open in daylight. Like if your business is shifting to tethered work I understand but I have a lot of experience with the H system. It's strengths are amazing but it's weakness in a wedding and portrait world are pretty glaring. Especially when you consider the cost. YMMV of course! Happy to keep seeing your work no matter what you shoot!
